摘　　要：针对碳纤维布(CFRP)加固钢筋混凝土构件可能发生的两种破坏形态(压区混凝土压碎破坏、CFRP拉断破坏),分别给出了简化计算公式和适用条件,并进行了有限元分析,与试验值进行了对比,吻合较好。According to the two probable failure modes (compression failure and CFRP rupture) of the RC structure member strengthened by CFRP,a simplified formula for evaluating the ultimate flexural capacity is presented and a finite element analysis is made with ANSYS software, the result of which is compared with the test result, indicating a good agreement between them.

关 键 词：碳纤维布(CFRP) 加固 破坏形态 抗弯极限承栽力
